Composite fireproof board easy for processing and preparation method thereof

ABSTRACT

A composite fireproof board easy for processing, splicing and installation is disclosed. The structure thereof includes, from top to bottom, a bottom layer, a lower reinforcement mesh layer, a middle layer, an upper reinforcement mesh layer, and a surface layer. The middle layer includes an organic frame and an inorganic fireproof material filled within the frame. The frame is provided with fixed grooves on edges adjacent to the fireproof material, and is further provided with through holes. A preparation method of the composite material fireproof board is also disclosed. The present invention adopts the inorganic material as a major material of the board, which has good fireproof performance and waterproof performance, is capable of phase-change energy storage, and achieves high stability and strength. The organic frame disposed on the periphery of the inorganic material enables the board to have good processability. Providing fixed grooves and through holes on the frame can achieve a firmer combination between the fireproof material and the frame, and prevent the frame from stripping off or cracking. Covering a reinforcement mesh layer and a thin-bedded inorganic material above and below the middle layer can increase the tenacity and strength, prevent cracking at the joint, and achieve a fireproof effect.

TECHNICAL FIELD

The present invention relates to a floor, and in particular, to acomposite fireproof board easy for processing and a preparation methodthereof.

BACKGROUND ART

A lock floor is made by providing grooves and tongues on adjacent floorboards and fixing the floor boards by fitting the grooves with thetongues. In the flooring process, the lock floor can be directly laid onthe ground without using any nails, glue, and keels, thereby preventingthe floor joint from cracking. Moreover, the floor is easy to installand can be repeatedly assembled and disassembled, so it is very popularon the current floor market. However, the lock floor is very strict withthe base material. Because the lock force of the lock floor dependsentirely on the joint between the grooves and tongues, the structure ofthe grooves and tongues needs to be very precise and smooth. At present,most lock floors use organic materials such as high-density resin asmajor materials. Such lock floors are advantageous in having goodprocessability. However, the organic board has two disadvantages:firstly, it is not resistant to high temperature and is deformed easilyby heat, and therefore the grooves and tongues will be deformed andfailed to be connected; secondly, it is not fireproof.

Inorganic boards such as glass-magnesium boards, magnesite boards,calcium silicate boards, cement boards, and the like have good fireproofperformance, as well as good heat conductivity, high stability, and goodstrength, thus being widely used in building partition panels, ceiling,door planks, and other fields at present. However, due to the poorprocessability of the inorganic boards, the processed structure ofgrooves and tongues can be easily cracked when being used for the lockfloor, resulting in a failure in connection between adjacent boards.
